WebApr 14, 2024 · The resting membrane potential is the result of the movement of several different ion species through various ion channels and transporters (uniporters, … WebThe sodium-potassium pump sets the membrane potential of the neuron by keeping the concentrations of Na + and K + at constant disequilibrium. The sudden shift from a resting to an active state, when the neuron generates a nerve impulse, is caused by a sudden movement of ions across the membrane—specifically, a flux of Na + into the cell. WebThe neuron cell membrane is partially permeable to sodium ions, so sodium atoms slowly leak into the neuron through sodium leakage channels. The cell wants to maintain a negative resting membrane potential, so it has a pump that pumps potassium back into the cell and pumps sodium out of the cell at the same time. reborns in the uk
